feat: add universal resolver

[dbluhm]

This PR merges the universal resolver plugin into main ACA-Py. This PR adds a couple new CLI args to configure usage of the universal resolver.

By default, the universal resolver is NOT loaded. If the --universal-resolver flag is given, without arguments, it will default to using https://dev.uniresolver.io for convenience. We might want to add language somewhere discouraging people from using this endpoint all the time. We should encourage people to use --universal-resolver https://my.universal.resolver.com to point to their own deployed universal resolver instance.

By default, if the resolver is loaded, it will retrieve properties from the universal resolver and use that to compile a regex that matches all supported DIDs. This regex will be used to determine if a given DID is supported by the resolver. Alternatively, the user can specify --universal-resolver-regex regex-one regex-two regex-three to manually configure what DIDs should be supported by the universal resolver. This is useful when you want to limit usage of the universal resolver to a known "trustworthy" set of DIDs or similar. The arguments to --universal-resolver-regex are compiled into a single regex on startup.
